I have difficulty about the utility of 'provide'. You have pointed out that
(provide 'daph)
simply announces that daph is a feature of the current emacs. Can it be any
name? The
manual states that "calling 'provide' adds 'feature' tothe front of 'features'
if it is not already
in that list". This suggests that provide should also use (provide
'daph-ideograms).
I guess that one could define the feature as 'daph' when using 'provide'. And
use the feature 'daph'
when calling 'require'. In this way, the 'daph' will be recognise the 'daph'
feature in the features variable,
but use the optional filename "daph-ideograms"
Thus
daph-ideograms.el
**********************
(provide 'daph)
test.el
*******
(add-to-list
'load-path "~/Admin/bin/gadi-1.0/typex/ziggurat-protowrit/daph-ideograms")
;; Load the Daph Package if it has not already been loaded.
(require 'daph "daph-ideograms")
--------
My load path is quite long, and wonder how this can be shortened by storing in
some other variable
before passing to 'add-to-list'.
